Abstract

The purpose of this study was to investigate the effects of short term resistance exercise on neuromuscular fatigue threshold (PWC_FT), strength, functional performance, and body composition in older adults. Twenty-three participants (71.2±6.0yr) were randomly assigned to 6 weeks of resistance exercise (EXE) or control (CONT). A submaximal cycle ergometer test, physical working capacity at fatigue threshold, was used to determine PWC_FT. Strength was assessed with predicted leg extension 1-RM and functional performance with time to complete 5 chair rises (CHAIR) and walk an 8-ft course (WALK). PWC_FT, 1-RM and CHAIR significantly (p<0.05) improved in the EXE (27%, 24%, 27%) compared with CONT (-0.1%, 7%, 6%), respectively. The results of this study suggest that short term EXE improved strength, functionality and the capacity to delay the onset of neuromuscular fatigue in older adults.
